To all whom it may concern:

Be it known that I, EDWARD.

borough of Brooklyn, city of New. York, State of New York, have invented certain new and useful Im rovements in -WI 'iting-,-

the accompanying drawings: Figure 1 is a view in longitudinal vertical sectlontaken adjacent the left hand side of the mabar 0 runs upon riage, of w c is shown.

chine: Fig. 2, a similar section taken'adFj acent 3 a rear elevation; Fig. 4, a detail plan view showing a controlling rock shaft and associated parts for governing the ositlon of the framestop that cooperate's wlth the mar in andtabulator stops on the carria showin -a modification or addition.

a is t e laten suitabl mounted-inn carch 1), b, are t e end plates ap ropriately connected bycross bars one of w 'ch At the front, the carriage runs bearing 01, and, at the rear, the H .a roller 0- mounted on a bracket c fast to the main frame. .Adjacent the rear of the carriage is a toothed margin upon a ball stop bar 6 upon whichare removably mount-- ed margin stops 6., there being one for the right hand margin and one for the left. In

' rear of thistoothed bar is a toothed tabutively thin,

lator sto barf upon which are ,removably or adjustab iy mounted any desired-number of tabulator stops f---preferably, flat and relaas seen m Fig. 3. Betweenthe bars e, f, is a verticallydisposedv lever g piv-' oted at h in a bracket h with the axis of the platen. The lever 9 extends downwardly from its ivotinside the rear plate of the frame, its

the upper end '5. of an upwardly. extending arm 'iiixed, to a transversely disposed rock inbearings in theside plates B. Hnss, a citizen of the United States, residing in the g e: and 1g, 5, a longitudinal vertical sectio'na .viewtaken adjacent the-left hand side of the machine.

upon an axis parallel ower vertically disposedbnd g being opposite and in front of f The arm 't'. has'also ad acent and in front of which stands the downwardly extending end m of a lever pivoted at m on the side of the bracket 0, and whose upper horizontally disposed end m has a lateral extension m faced with leather or other suitable friction mateitial. When the upper end of this lever is rocked upwardly. it engages the horizontal part n, of the angular rack 12. ivoted at n. 0 isthe usual pinion, engaged y. the rack, turning with the toothed escapement wheel 0.

Referring, for instance, to Fig. 2, the vertically disposed sto lever g pivoted on the frame stands is hel by a spring g in normal position in which it will engage the margin stops 6 and arrestthe carriage. To release the carriage for printing an 'additionfildetter or letters at the right hand margin, the up er end of the lever 9 may be rockedlrearw'ar' y' out of the ath of the mar block by action of end 'i 0 arm 2'. when t e' latter is rocked rearwardly. For tabulator Work, a greater".

extent of movement-rearwardly of the u per end of lever g Wlll carry it into the pat of the tabular-sto s f before which, however, i

the rack bar is ted, against the tension of its springs n", from engagement with the pinion' 0 by action of the part '5 of the arm i. upon the lower end m of the rack release lever. The different lengths of movement for co-operative'action' of the stop lever g and margin stop e and of said lever with the rack release'lever and tabular sto sf, is afforded by,moving the arm '5 on' t e rock shaft k through arcsof. diiferent length. .In Fi s. 1 and 2 this is accornplished by key levers aving vertically movable finger pieces in the key board, and arranged respectively adjacent opposite sides of the machine.

. The key lever 1) arranged ad'acent the left hand side of the machine is designed for operating the vertically disposed stop lever g in conjunction with the tabular stops and is adapted therefore to e'st. range of rearwar movement. The key lever rocks about an axis p being sustained innormal position by any suitable s ring such as 1); An extension 3 of the ever above its axis extends over t e rock shaft k and has in it a laterally projecting pin or stud 1) that normally lies against the rear face of a radial projection is idly secured to the gve'that lever its greatrock'shaft. When the ey lever is depressed,

' upon the projection 7c rocking the shaft k to such extent as not only to effect, as described, release of the rack, but also to carry the 'lever 9 into the paths of the tabular stops. At the opposite or righthand side of the machine, Fig. 2, is a similar key lever g "turning also about'the'axis p which may be a rod extending transversely of the machine between its side plate. upward extension Q1 of the lever extendsover the rock shaft 7c and has'a lateral pin g that acts u on a radial projection is on the rocksh'aft ut. is normally separated therefrom by a suitable interval as seen iii-Fig. 2. 011 de. ression'of this-ikey, no movem'ent of the rec shaft oc-- curs until the pin 'q icomes incontact with the Y 'a'rmk fwhen,'as'idescribed, a -sufficient forward movemntis imparted to the arm i to carry the; leverg rearwardl'yout ofthe path of the margin stop, butnot-sufficiently great to release theraek from t e pinion 0 nor causethe lever'tofengagethe tabular stops.

A ;modification' illustratedi in Fig. 5 consists in providing at the front of the machine a horizontallydisposed push pin 1' equippedwith an ordinary finger piece r and-jointed at its rear end to a'lev er s pivoted at s and having applied to it, above its pivot, a

spring 3 the reaction of which tends to throw the upper end of the lever forward and maintains the push pin in normal projected position. The lower end of the lever .is equipped with a roller t that bears upon the upper edge of the key lever p. Instead, therefore, of depressing the key lever by means of its finger piece, it may be depressed and the described operations accom lished by pushing the stem 1" inwardly. Wlth this arrangement, if desired, the lever (for instance p) need not have a finger piece in the key board, but may be cut off, if desired, at a suitable point such as that, for instance, indicated by the dotted line ac. The primary purpose ofthis arrangement, however, is to dispense with the key lever g. By employment of the devices s, 1", the lever 1) may be depressed only sufficiently for to cause stop g to disengage the margin stop, and by complete depression of p by means of its finger ary 3, 1905. This application is based upon subject matter not disclosed in the said application No. 244,022.
